Conciseness

Every section earns its place: auth header format, three endpoints, a compact parameter table with a concrete JMESPath example, a minimal response schema, one worked curl command, error handling, and routing disambiguation. Nothing explains concepts Claude already knows, and the content-safety note is skill-specific guidance about untrusted feed data rather than padding. Lean and efficient matches anchor 5.

Actionability

The worked example is copy-paste ready ("curl -s --get -H 'X-WorldMonitor-Key: $WM_API_KEY' ... --data-urlencode 'page_size=25' | jq ..."), endpoints are exact URLs, parameters are tabulated with types and constraints, and the response shape is shown field-by-field including the degraded-snapshot signal ("fetchedAt: 0 or dataAvailable: false"). Fully executable and covers the common cases — anchor 5.

Workflow Clarity

The entry point and escalation path are explicit: "Start with `list-climate-disasters` for event records, then use anomalies or climate news when the user needs broader context." The Errors section provides recovery feedback for each failure mode (401 missing key, 429 retry with backoff, seed-unavailable signals to retry later). This is a simple, single-purpose retrieval skill with no destructive or batch operations, so the simple-skill exception applies and the single action is unambiguous.

Progressive Disclosure

Sections are clearly labeled and the References section points one level deep to well-signaled external resources (OpenAPI operations ListClimateDisasters/ListClimateAnomalies/ListClimateNews and the auth matrix). However, the ~90-line body inlines the full response schema and complete parameter tables — content that would sit appropriately in a reference file if the skill grows. Good structure with minor organization gaps matches anchor 4 rather than the fully split structure of anchor 5.

Specificity

"Retrieve climate-relevant disaster events, anomalies, and climate news" names the domain and three distinct retrieval targets that fully cover the skill's scope, though all are variations of a single "retrieve" action rather than multiple distinct operations. Anchor 4 (several specific actions, minor gaps) fits better than 3 because coverage of the skill's own capabilities is comprehensive.

Completeness

The description explicitly answers both questions: "Retrieve climate-relevant disaster events, anomalies, and climate news" states the what, and "Use when the user asks about floods, cyclones, droughts, heatwaves, wildfires, or climate disruption" states the when with concrete trigger phrases. This is an exact match for anchor 5.

Trigger Term Quality

"floods, cyclones, droughts, heatwaves, wildfires, or climate disruption" gives good natural-language keyword coverage a user would actually say, but misses common synonyms such as hurricanes, storms, extreme weather, or natural disasters. Good coverage with a few natural terms missing matches anchor 4, not the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The climate-hazard niche is clear with distinct trigger terms, but "wildfires" overlaps the dedicated wildfire skill ("GET /api/wildfire/v1/list-fire-detections") and "floods" is broadly adjacent to general disaster intelligence. Mostly distinct with minor overlap risk against closely related skills matches anchor 4.
